摘要

Nanoparticles (NPs) have garnered a lot of interest in sectors like medicine, cosmetics, food, and pharmaceuticals for antibacterial catalytic properties, reduced toxicity, and easy production. Biological synthesis of silver nanoparticle (AgNPs) is considered as green, eco-friendly, and cost-effective approach; therefore, Azadirachta indica extracts were utilized for a dual role of fabrication and functionalization of AgNPs. Optical and physical characterizations were achieved for confirming the biosynthesized AgNPs. P:SEM 8.46.247images 10 detectedOn: Wed, 04quasi-spherical Jan 2023 AgNPs06:13:8of44.04 to 66.50 nm. Some of potent phytochemicals like flavonoids and proteins from zadiachta indica formed a strong coating or capping on the AgNPs Copyright American Scient fic Publishers without affecting their secondary structure by interacting with Ag+ ad NPs for the formation of AgNPs. AgNPs exhibDelivered by Ingenta ited strong antibacterial activity (MIC 10 mu g/ml) against multidrug-resistant bacteria Enterococcus faecalis; at different concentrations, no IC50 values were recorded for AgNPs as well as Azadirachta indica signifying low cytotoxicity in the exposed concentration range. The DNA degradation activity of AgNPs through the TUNEL assay revealed no significant increase in the overall FITC mean fluorescence intensity as well as a DNA fragmentation index with 5.45% DNA damage (10 mu g/ml AgNPs). Drug uptake of AgNPs was also investigated through a permeability assay via Caco-2 cell lines at test concentrations where apparent permeability was detected as moderate.
